Costeño Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Grab a coffee and let’s talk about what’s comin’ up at Costeño Beach.

First thing you gotta know: the swell direction is locked in from the northeast for the whole run, and this spot is wide open to it. The water temp is sitting pretty average for this time of year, so no surprises there – just your usual warm bath.

Now, the surf. The first few days are a bit of a mixed bag with some solid, chunky swell but the wind is a pain. Friday the 14th starts with a 7ft northeast swell (moderate energy at 596) but it’s cross-on and a bit messy. Not worth paddling out for. That afternoon, though? The swell jumps to a powerful 10ft (1218 energy) – that’s a beast. But look, that’s way too big for this place, and it’s a beginner-friendly beach. That’s expert territory, if you’re crazy enough. The wind stays light cross-on, but with that size, it’s gonna be a washing machine. Saturday the 15th is a write-off, with 8ft and a moderate breeze making a total mess. Sunday the 16th drops a little, but it’s still not clean.

The real standout, the one you’ve been waiting for, comes on Thursday the 20th. The swell drops to a more manageable 5ft in the morning, still out of the northeast, and the wind goes glassy. That’s right, dead glass. The energy is a solid 499, and it’s clean as a whistle. Thursday afternoon is the same story: 5ft, glassy, perfect for a long session. The break is consistent, so you’ll get waves. Expect a crowd, though – this spot is known to get busy, and with conditions this good, everyone’s gonna be out. That’s your best bet, no question.

After that, the swell fades. We get a few days of small, weak waves (under 5ft) with light cross-on winds, nothing to get excited about. There’s a brief window on Wednesday the 19th, late afternoon, with 4ft and glassy conditions, but it’s a short-period swell (7 seconds) and the energy is low (200). It’s surfable, but ordinary.

The second week is pretty quiet. The swell stays small, around 4ft to 5ft, with mostly cross-on or onshore winds. Nothing stands out. There’s a hopeful little blip on Thursday the 27th morning with a 5ft swell and glassy wind (301 energy), but it’s a one-off. The rest of the run is just small, weak leftovers.

Honestly, if you can pick a day, make it Thursday the 20th of August. That’s the one. Otherwise, you’re looking at a long stretch of pretty average conditions.

Rusty.
